How to automatically close an alert after a certain time React Native

问题

I would like to automatically close an alert after a couple of seconds without having the user do it themselves.

If possible I would like to do this using Alert (not AlertIOS), but if only AlertIOS has it then I guess I have no other choice.

Thank you very much!

I suggest you use Modal component

<Modal
  animationType={"slide"}
  transparent={false}
  visible={this.state.modalVisible}></Modal>

So you can call setTimeout() in your function to update the state variable modalVisible to show / hide it. More examples can be found here from the official doc (https://facebook.github.io/react-native/docs/modal.html)
